There was a seam burst on the 3rd dryer top felt, the 3rd bottom felt was also damaged and dryer can 3 was knocked off its rocker. The root cause was still being investigated, but the felt chemical treatment prior to the burst was one of the possibilities (dodo for me). I left at about 3 AM, got 6 hours of rest. The machine shutdown is extended and estimating start up time is 1 PM. I would NOT be around for that!!
